This post is mainly excerpted from Dr. Timothy Keller’s excellent Preaching in a Secular Culture.

His advice is not just for preachers but is also useful for teaching a Bible study or giving a short testimony. What we say and how we say it should point people to Jesus. I’m only presenting his four main points and some quotes. I’m only scratching the surface here of a very rich nine-page document. It’s worth your time to read and absorb it. The rest of this post are quotes from Dr. Keller’s original work.
